To all ooo/loin1 t may concern:

Be it known that l, JOHN G. WEBB, a citizen of the United States,residing 'at Richmond, in the county ot'Hem-ico, State of Virginia, haveinvented certain new and useful Improvements in Molds for PluralCastings; and l dohereby declare the folvlowing to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

breaking them down into lighter billets, eX-

cept in case of small ingots cast trom crucibles7 in which case theingots are castin vertical position.y one ingot at a time, amethod thatis too slow in the handling of lar( e quantities ot molten metal.

everal methods ot group pouring have been employed, but those with whichI amA 'familiar are unsatisfactory for the manufacture of very smallsteel ingots because of excessive quantities oi' discard metal in thelong runners employed, because of ei;- pense due 'to the complicity andnumber ot runnerbricks, iron bases or retaining flasksror the molds andsimilar adjuncts and because of the labor and handiwork involved, allincreasing the ultimate cost of the product. In practising the presentinvention,

the various adj uncts that determine the ex- Dense of firstA cost. arereatl Y reduced as is also the expense of manipulation. The runnerbricks areeomparatively few, the runners are short and can be shaped toconsti- 'tute an additionalshape or ingot and no re- .tainer flasks arenecessary. rJhel molds are simply set up on a plane surface, ashereinatter explained. y

The use et molds such as hitherto employed, has necessitated anexpenditure of 1time and labor in the stripping and resetting that islargely obviated by the novelty of mold and the method ofhandlinghereinatt-erf explained.

Fig. 13 is a perspective view showing a vertical arrangement of molds,the runner and the connected portions of the molds being in sectionalperspective. y

Referring rst to Figs. Vl to 5 inclusive oli' the drawings there isemployed a runner brick 2O having a. central longitudinal passage 21from which lead at regularv intervals the laterally directed' gates 22,the passage 21 terminating short of the ends of the runner brick. Midwayof the ends of the brick is a pouring gate 23 formed through its upperwall and with which is engaged the usual sink head 24. y

In connection with the runner brick 20 there is employed at each side aseries of molds 25, which in the arrangement shown -in Fig. 3, consisteach of a rectangular body having in two of its opposite longitudinalfaces the longitudinal bha-nnels 27 that extend through one end of themold and terminate short of the opposite end. Thus the mold, except atthe portion beyond the molds.

trated kin Fig. 5, is shown but without the supports.

In Figs-11 and 1.2 of the drawings is shown an embodimentr of theinvention in which there is employed a contral, hollow runner brick 40that is closed at its lower end Ythrough the medium of a plate e uponwhich itrests, this core or brick lbeing crosssectionaliy rectangularand having gates 41 in its side walls. The core or .brick beingrectangular in cross-section, the gates are thus disposed in a pluralityof horizontal series, each including four gates. The series of gates areequally spaced vertically'of the brick.

In connection with the brick 40 there is employed a plurality ofvertical series. of molds 42 which are illustrated of the H type andwhich series correspondin number to the sides of the bric-k. The molds42 are laid up with their webs horizontal andthe open ends of theirlongitudinal channels 43 in thedirection of the core brick, which isvertical, as illustrated. The molds being disposed in vertical series,one upon another, the upper-channel of each mold, eX- cepting theuppermost one, coperates with the lower channel of the mold next above,to constitute a Imold form, with each of which communicates a gate ofthe runner brick. brick is arranged a sink head 44.

Each mold is provided at its closed end with an eye 45 which opens inthe direction of theside opening of the mold channels so that when themolds are assembled as illustrated, these eyes will register verticallyto' receive a carrying and suspending bar 46. After the cast has beenmade, at which time the poured metal passes from the runner brick to theforms ofthe several molds, cach series of molds is picked up by means ofa tackle connected with the bar 46 and is hung from the bar by placingit upon supports in the same manner previously d'escribed. The molds arethen separated sucports the inner end portions of the series ot" molds,there being provided an additional .Upon the upper end of the runnersupporting plate 'f for the outer end portion of each series of molds.These platese and f are carried by a supporting cross-shaped frame gthat holds the molds above the level of the casting lioor.

In Fig. 13 ofthe drawings, there is shown an arrangement of molds 50, ofthe H type that are disposed vertical with their open ends upwardly andhaving supported thereon a runnerrbrick 51 from the central longitudinalchannel 52 of which lead gates 53, each to a pair of cooperatinglongitudinal channels 54 of a pair of molds.Y The pouring gate 55 isthroughthe opposite wall of I the brick from the gates 53 and there isassociated with it a sink head 56. -At the lower or closed ends of themolds 50 are the eyes 57 that register with each other to receive acarrying and supporting bar 58, the molds themselves being djisposedloetween suitable sills 59 to support them with the eyes out of Contactwith the surface u on which the varrangement is erected. The pouringoperation is of course apparent while the manner of stripping the ingotsfrom the molds is the same as that previously described. y

V It will of course be understood that either the H type or the U typeof mold may be employed in each of the various arrangements illustratedwhile the runner brick in each in stahce forms also a mold to produce ausable shape,

It will also be understood that a clamp may be employed for holdingtogether the molds of the series in eachinstance.

In Fig'. 14 of the drawings-there is illustrated another equipment fordischarging the'ingots from the molds. In this equipment, instead ofpassing a4 bar such as 32 in F ig. 7, through the eyes 3l, there isemployed a spreader bar 60 to which is connected the lifting chains 61and from which'.

depend at regular intervals, the hanger chains 62 having hooks 63 attheir,` lower ends that engage the eyes 3l, respectively. The spacing ofthe hanger chains 62 is slightly greater than the spacing of the eyes 31when the molds are'in ingot-receiving positions. Thus, when the bar 60is lifted,l the individual molds are suspended from it through themedium of the chains 62 and they swing apart by gravity, this separationof the molds permitting the discharge of the ingots 63', as will beunderstood. In Fig. 14 all of the ingots excepting one have dropped fromtheir molds. It will be, of course, understood that after th'e dischargeof the ingots by this method, the molds may be returned to the moldlicor and again set up with whatever specific arrangement is desired.

What is claimed is:

1.v A composite mold comprising a runner brick having a plurality ofoutlet gates, and

e plurali@r 'o' mold members having each a plurality oliililre moldfaces and associated with 'eachgate and roviding a mold form arranged toreceive rom that gate, the association ot mold members at each gateinclurling a like mold lace of a mold member of another association.
